Then, with this as the center, the family conducted large-scale drilling and finally discovered a miniature spirit stone vein.

Sixty pieces of spirit were harvested. Not one high-level spirit stone was found, but two pieces of Purple Sun Chalcedony were fished out from the spirit pond.

How should I put it, if Zhang Cheng in the Qi training period discovered such a miniature spirit stone vein, he would be happy to death. Now, Zhang Cheng finally understands what is useless.

Another trivial benefit is that after discovering this miniature spirit stone vein, there will not be a second spirit stone vein within a thousand miles from here.

It was relatively easy for Zhang Cheng to find the remaining spirit stone veins nearby.

This time, the messenger incense was lit, and people from the sect came as usual. However, Zhang Cheng returned to Taisumen Mountain Gate headquarters once after the people from the sect confirmed the spirit stone veins.

This time, Zhang Cheng discovered a semi-great power of miniature spirit stone veins, so he replaced it with fifteen Shangyuan Pills that he had used to improve his cultivation in the Zifu period.

Although the cultivation levels of Zhang Cheng and Liu Yunyan have not improved in the past two years, without the elixirs from the Zifu period and the demon pills from the Zifu period, the progress of their cultivation has been very slow. Now the two of them have

They are all still on the first floor of Zifu.

You don’t have the time to sit in seclusion and meditate for a long time to absorb the spiritual energy of heaven and earth, and there is no Zifuqi Waidan to enhance your cultivation. It is not difficult to understand why it is difficult to improve your cultivation.

The monsters in the Zifu period are basically either the tyrant of a certain place, or the leader of a large group of foundation-building monsters. If they want to enter the buffer zone here, the Jindan Zifu monks on border patrol will also take action to kill them after they find out. After all, this is

A large amount of monster resources.

Therefore, the buffer zone in this area will only have foundation-building monsters passing through at most. If you want to go deep into the range controlled by monsters, let alone two Zifu monks in a family, even seven Zifu monks in a family will not be enough.

Zhang Cheng has known for a long time that cultivating to become an immortal is definitely easier in the early stage, but becomes more and more difficult in the later stages. You can see this clearly by looking at the composition of the sect. The lower the people are, the more people there are.

After exchanging Shangyuan Dan, Zhang Cheng and his six wives continued to explore for mines.

According to Zhang Cheng, it is different from the foundation building period. Everyone must be prepared to stay in the Zifu period for a long time. You can understand it when you see that Zhang Cheng and Liu Yunyan are still on the first level of the Zifu.

Although two pieces of Purple Sun Chalcedony are enough for two people to try to open a Zifu, Zhang Cheng's idea is that it is best for our family to use three or four pieces of Purple Sun Chalcedony to open the Zifu, so that the combat effectiveness in the Zifu period will be

Much higher.

In the future, all the spirit stone veins within the Taisu Sect's control will be exhausted. At that time, in order to expand, the sect will naturally have no choice but to go to the monster's current control area to find the spirit stone veins.

When the time comes, a family of seven will have to fight against the Zifu monster, or even escape from the Golden Core monster. If each person's combat power is doubled, the seven Zifu monks can be used as fourteen Zifu monks.

It's not that others don't want to use this method, but they can't get so much Purple Sun Chalcedony. Even if the sect is the descendant of the Golden Elixir Nascent Soul cultivator, they usually have a Purple Sun Chalcedony. After all, the Golden Elixir Nascent Soul cultivator has a long lifespan.

There are many people.

"Although we have only obtained two pieces of Purple Sun Chalcedony in the past two years, even the foundation-building monks of the sect will not be able to obtain one piece of Purple Sun Chalcedony in ten years. Time is on our side."

Now Zhang Cheng has also discovered the significance of finding this miniature spirit stone vein, which shows that his probability-based carpet prospecting is not useless.

Although Zhang Cheng has not found the few remaining spirit stone veins in this buffer zone, he already has their approximate locations on the map.

Although there is an approximate location, it is still calculated based on a radius of thousands of miles.

Each region still has to be searched on a yearly basis. This is still the case with the Luoyang Shovel, which makes the prospecting speed dozens of times faster.

Come to think of it, if the spirit stone veins were really that easy to find, it would have been looked over many times before it would be my turn to prospect in the buffer area.

Nineteen months later.

"Xuantie. There should be a medium-sized spirit stone vein nearby. Look for it."

The medium-sized spirit stone vein discovered this time was better than the medium-sized spirit stone vein discovered by Zhang Cheng first. Seven pieces of purple sun chalcedony, 32 pieces of high-level spirit stones, and 600 pieces of medium spirit were recovered.

There are also the ten most important merits for Zhang Cheng and Liu Yunyan now, which can be exchanged for ten bottles of one hundred Shangyuan Pills. It has been more than three years since Zhang Cheng and his eldest wife Liu Yunyan opened the Zifu, and each of them has eaten seven or eight pills.

Shangyuan Dan, isn't it just about cultivation? It's still the first level of Zi Mansion.

Follow the procedures, light the incense that spreads the message to thousands of miles, and return to the sect to exchange for the Shangyuan Dan. Then the family goes to Fangshi to rest for a while.

Now even Liu Yunyao has already reached the stage of perfecting the ninth level of foundation building. However, this time, according to Zhang Cheng's idea, three people will be given priority based on their age to open the Zi Mansion first. The second, third, and fourth wives, Liu Yunting, Liu Yunrui, and Liu Yundai each took it.

Three pieces of purple sun chalcedony enter the quiet room of the wing.

Compared with when Liu Yunyan, who was seventeen years old at the time, opened the Zi Mansion, the second, third, and fourth wives had accumulated more powerful magic power, and they had also polished their magic power in the past three years. With the help of three pieces of Purple Sun Chalcedony, there was no danger when opening the Zi Mansion.

, three days later the three wives came out of seclusion almost at the same time.

Zhang Cheng's gift to his second, third and fourth wives to open the Zi Mansion was two bottles of Shang Yuan Dan each. Liu Yunyan, as the eldest sister, gave each of his second, third and fourth sisters two cold iron swords.

After living in Fangshi for another month, the family relaxed and rested. After eating a hundred Shangyuan Pills, Zhang Cheng, Liu Yunting, Liu Yunrui, and Liu Yundai all entered the second floor of Zifu, and Liu Yunyan entered the third floor of Zifu.

Both Zhang Cheng and Liu Yunyan can easily control two third-level magic weapons, and Liu Yunting, Liu Yunrui, and Liu Yundai on the second floor of Zifu can also barely control two third-level cold iron swords.

Now that the family's strength is not up to par, it is definitely not enough to cross the border city to go to the monster area. But in the buffer zone, there are no monsters that can threaten the family.

At the combat meeting before departure, Zhang Cheng took out a map and gave instructions:

"Based on the distribution of spirit stone veins on this map, it is only right that there is a spirit stone vein nearby and in this attachment. Now that we have added three Zifu monks, the prospecting speed is faster. Our current

The mission is to find the spirit stone veins in these two places. Yunjiao and Yunyao’s hope of opening up Zi Mansion lies in these two places."

Eight months later, a medium-sized spirit stone vein was discovered, and six pieces of purple sun chalcedony, nineteen pieces of high-level spirit stones, four hundred pieces of medium spirits, and ten great merits were recovered. Fifth wife Liu Yunjiao and Liu wife Liu Yunyao both opened the Zi Mansion.

.

After eating one hundred Shangyuan Pills, Zhang Cheng advanced to the third floor of Zifu, Liu Yunjiao and Liu Yunyao advanced to the second floor of Zifu, Liu Yunyan and other sisters slightly reduced their ration of Shangyuan Pills.

Seven months later, what was probably the last small spirit stone vein in the buffer zone was found by Zhang Cheng and his family, and they recovered eleven high-level spirit stones, three hundred medium spirits, and four pieces of Purple Sun Chalcedony.

The three great powers were exchanged by Zhang Cheng for 30 Shangyuan Pills. Because they were not enough points and were not enough at all. In addition, no one in the family except the mother-in-law who had not seen each other for several years could use the Purple Sun Chalcedony. The family discussed it and got it.

I took out a piece of Purple Sun Chalcedony and exchanged it for 60 Shangyuan Pills in the Zongmen General Affairs Hall.
